1/2" Inline Coupler for Pex

Decided to run my garage door wires in pex tubing so i can clean up my garage ceiling. Since this is not what PEX was intended for i made my own couplers/adapters. This one is a straight inline coupler for 1/2" Pex tubing. Outer diameter is 19mm, inner diameter is 16mm for 15mm on each open end and 14.8mm for the core of it. 1/2" Pex outer diameter is about 15.8mm so there is .2mm of room to work with. The fit is snug and no glue or anything is needed to secure the pex in place. Printed this coupler standing upright with supports
